In the earlier patches, the SPL/TPL fraamework was introduced.
For SD/SPI flash booting way, we introduce the SPL to enable a loader stub. The
SPL was loaded by the code from the internal on-chip ROM. The SPL initializes
the DDR according to the SPD and loads the final uboot image into DDR, then
jump to the DDR to begin execution.
For NAND booting way, the nand SPL has size limitation on some board(e.g.
P1010RDB), it can not be more than 4KB, we can call it "minimal SPL", So the
dynamic DDR driver doesn't fit into this minimum SPL. We added the TPL that is
loaded by the the minimal SPL. The TPL initializes the DDR according to the SPD
and loads the final uboot image into DDR,then jump to the DDR to begin execution.
This patch enabled SPL/TPL for P1_P2_RDB to support starting from NAND/SD/SPI
flash with SPL framework and initializing the DDR according to SPD in the SPL/TPL.
Because the minimal SPL load the TPL to L2 SRAM and the jump to the L2 SRAM to
execute, so the section .resetvec is no longer needed.

ARM: tegra: use a CPU freq that all SKUs can support
U-Boot on Tegra30 currently selects a main CPU frequency that cannot be
supported at all on some SKUs, and needs higher VDD_CPU/VDD_CORE values
on some others. This can result in unreliable operation of the main CPUs.
Resolve this by switching to a CPU frequency that can be supported by any
SKU. According to the following link, the maximum supported CPU frequency
of the slowest Tegra30 SKU is 600MHz:
According to that same table, the minimum VDD_CPU required to operate at
that frequency across all SKUs is 1.007V. Given the adjustment resolution
of the TPS65911 PMIC that's used on all Tegra30-based boards we support,
we'll end up using 1.0125V instead.
At that VDD_CPU, tegra3_get_core_floor_mv() in that same file dictates
that VDD_CORE must be at least 1.2V on all SKUs. According to
tegra_core_speedo_mv() (in tegra3_speedo.c in the same source tree),
that voltage is safe for all SKUs.
An alternative would be to port much of the code from tegra3_dvfs.c and
tegra3_speedo.c in the kernel tree mentioned above. That's more work
than I want to take on right now.
While all the currently supported boards use the same regulator chip for
VDD_CPU, different types of regulators are used for VDD_CORE. Hence, we
add some small conditional code to select how VDD_CORE is programmed. If
this becomes more complex in the future as new boards are added, or we
end up adding code to detect the SoC SKU and dynamically determine the
allowed frequency and required voltages, we should probably make this a
runtime call into a function provided by the board file and/or relevant
PMIC driver.

baord_init_f takes one argument, boot_flag. It has not been used for
powerpc, until recently changing to use generic board architecture.
The boot flag is added as a return value from cpu_init_f().

powerpc/freescale: Change the return value of mac_read_from_eeprom()
The return value has not been checked by its caller, until recent change
of using generic board architecture. The error of this function is not
critical enough to hang the system. Printing the warning message is enough
to catch user's attention. U-boot should continue to boot to give user
a chance to fix the EEPROM. Chaning the return value to 0 to avoid hanging
in the board_init_r().

powerpc/mpc85xx: Ignore FDT pointer for non-QEMU in cpu_init_early_f()
The pointer of device tree comes from r3 for QEMU. This is not the case
for normal SoCs out of reset. Having gd->fdt_blob as 0 is important for
other functions to detect the non-existence of device tree.

powerpc/mpc8572ds: Increase u-boot size to 768KB
U-boot image has grown and exceeded the predefined 512KB. Increasing to
768KB to align with other powerpc boards. Tested on MPC8572DS for 32-
and 36-bit targets with NOR flash boot. NAND boot is not covered by
this patch.
Also update board maintainer for these boards.

powerpc/mpc85xx: Update TLB CAMs in relocated mode
We want to use the TLB mapping helpers in relocated mode as well. These helpers
need to have awareness of already occupied TLB entries. We already had them in
sync in non-relocated mode, but need to resync them when we move into relocated.

PPC 85xx QEMU: Always assume 1 core
We only need u-boot to bother about a single core in the QEMU machine.
Everything that would require additional knowledge of more cores gets
handled by QEMU and passed straight into the payload we execute.
Because of this setup, it would be counterproductive to enable SMP support
in u-boot. We would have to rip CPUs out of already existing spin tables
and respin them from u-boot. It would be a pretty big mess.
So only assume we have a single core. This fixes errors about CONFIG_MP
being disabled.
